Abstract
1453455 Grinding tyres GENERAL TIRE & RUBBER CO 6 Nov 1973 [13 Nov 1972] 51547/73 Heading B3D [Also in Division G3] Apparatus for balance correcting pneumatic tyres comprises means for rotating an inflated pneumatic tyre, grinding means for removing rubber from the tyre, a light source for illuminating reflective means, previously applied to the tyre, on each revolution of the tyre, a light sensing means for sensing light reflected by the reflective means, and outputting an electrical signal responsive to reflected light sensed, and actuating means for operating the grinding means to remove rubber from the tyre in response to the output from the light sensing means. In the illustrated embodiment, a pneumatic tyre, which has been tested for balance and on which a mark 11 has been placed diametrically opposite the portion of the tyre from which rubber is to be removed to correct imbalance, is placed on a chuck 13, inflated and rotated. Upon inflation a switch 37 is automatically actuated to cause power to be supplied to a servo-mechanism 29, which controls a ram 27, to move grinding wheel 21 towards the tyre tread. Sensor 30 on engaging the tread prevents further movement and the wheel is held in a "retracted" position adjacent to but not touching the tread. The wheel is moved into engagement with the tread when light from a source 18, reflected by a reflecting strip 16 previously applied to the tyre and of a width corresponding to the amount of rubber to be removed, is sensed by sensor 19. When sensor 19 no longer senses reflected light the grinding wheel is returned to its "retracted" position. The number of revolutions of the tyre is controlled by a timer forming a part of switch 37. When the timer "times out" the switch 37 is switched OFF, and the hydraulic ram 27 is automatically drained to allow the sensor 30 to move away from the tyre. The force with which the grinding wheel is urged against the tyre is controlled by the width of the reflective strip 16. The potentiometers 44, 47 respectively, control the "retracted" position of the grinding wheel and the gain of the amplifier 39. In an alternative embodiment (Fig. 3, not shown) a mark or marks on the tyre indicative of the amount of rubber to be removed are sensed by a control circuit as a corresponding number of pulses and the pulses automatically control the number of actuations of the grinding wheel. Instead of the grinding wheel moving, as illustrated, into contact with the tyre, the latter may be moved into contact with the grinding wheel or the tyre and wheel may be in continuous contact with the wheel being rotated relative to the tyre to effect grinding.
